being provided for causing the exit of the gas at an angle with respectto the movement of the air whereby the discharging air will exert asucking action on the gas which will to a great extent counter-act thepressure of the gas and consequently cause a short compact flame whichwill be intensely hot.

An important object is the provision of a 7 device of this characterwith which may be used pre-heated air under normal or higher pressure,as preferred.

An additional object is the provision of a device of this characterwhich will be simple and inexpensive in manufacture, highly eflicient inuse, durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the inventionconsists in the details of construction to be hereinafter more fullydescribed and claimed, and illustrated in the accompanying drawings inwhich Figure 1 is a side elevation of the burner,

Fig. 2 is a longitudinal sectional view,

Fig. 8 is an elevation of the tip member, and

Fig. i is a cross sectional view on the line 4-4: of Fig. 2. g

Referring more particularly to the drawings, the numeral 10 designates abody which may be formed as a casting and which is provided internallywith a partition 11 defining air and gas compartments 12 and 13,respectively. The body 10 is provided with holes 14 and 15 communicatingrespectively with the air and gas chambers 12 and 13.

At its sides the body 10 may be provided with lateral extensions 16 toprovide securing means.

Threaded into a hole in one side of the body 10, this hole communicatingwith the chamber 12, is a cylindrical tube 17 and threaded into ahole-in thepartition ll and communicating with the chamber 13, is a pipe18 which extends co-axially through the tube 17 and which terminatesshort of the outer end thereof. By this construction it will be seenthat the annular space19 is provided betweenthe'tube 17 and pipe '18 andthat this space communicates with the chamber 12. a i

Threaded upon the outer end of the pipe 18 is a tip 20 which has itsouter end closed,

as shown at 21, and this outer closed end is provided with a circularseries of holes 22 which are inclined at an angle of 45 with respect tothe longitudinal axis of the 1nembers 17 and 18. These holes 22 are thegas discharge openings. Formed integrally around the inner periphery ofthe tip 20 are spirally arranged ribs or vanes 23 and the spaces betweenthese ribs or vanes are for the passageof air. v

In the operation of the device it will be seen that when air and gas aresupplied to the burner, the gas will pass through the pipe 18 and outthroughthe holes 22 andv the air will pass through the annular-space 19and between the ribs or vanes 23, the

air being given a whirling motion owing.

that I have thus provided a simple device of the character specifiedwhich consists of the minimum number of parts, which will therefore beinexpensive in manufacture, not liable to derangement, and which willyet perform all the functions for which 'it is intended.

While I have shown and described the preferred embodiment of myinvention, it is of course to be understood that I reserve the right tomake such changes in the form, construction, and arrangement of parts aswill not depart from the spirit of the invention or the scope of thesubjoined claims.

Having thus described my invention, I claim: v

'1. A device of the character described comprising a body provided withair and gas chambers having inlet openings, a tubu lar member connectedwith said body and said closed end being provided with a plu rality ofgas discharge holes and the outer periphery of said tip being providedwith a plurality of spirally arranged ribs defining spiral passagesthrough which the air passes, the'air being thereby given a circularmotion. J

2. A device of the characterdescri-bed comprising a' body provided withair and gas chambers having inlet openings, a tubular member connectedwith said body and communicating with the air chamber therein, a pi eextendingconcentrically through said tu ular member and communicatingwith the gas chamber, and a tip on the end of said pipe having its outerend closed, said closed end. being provided with a plurality of gasdischarge holes and the outer periphery of said tip being provided withaplurality of spirally arranged ribs defining spiral passages throughwhich the air passes, the air being thereby given a whirlingmotion,'said gas discharge holes being at an angle with respect to thelongitudinal axis of the gas conducting pipe.
